Allelopathic Effect of Anogeissus pendula Edgew. and Grewia flavescens A. Juss on Desmodium Species in Alwar district of Rajasthan

Abstract

The effect of leaf leachates of Edgew. and A. Juss was evaluated on growth of the three Anogeissus spendula Grewia flavescens species of . reduced the percent seed Desmodium Anogeissus pendula in Alwar district of Rajasthan (27 4' to 28 4'N and 76 7' to 77 13'E) o o 0 o germination of from 85 in control to 43 at 2% concentration, from 80 in control to 50 at 6% concentration and D. repandum D. gangeticum D. triflorum Grewia flavescen from 78 in control to 28 at 0.1% concentration of leaf leachates. However, the leaf leachates of had similar effect on sthe former, whereas, it has more adverse effect on the seed germination of later two species. The leaf leachates of both the species also reduced the elongation of radicle and plumule of three species; however, the adverse effect of leaf leachates of was more Desmodium Grewia flavescens severe than that of the other species. Among the three species, the allelopathic effect of and Desmodium Grewia flavescens Anogeissus pendula was more severe on as compared to the other two species. Thus it may be suggested that the population of three species of Desmodium triflorum Desmodium Anogeissus pendula Grewia flavescens is partly regulated by the allelopathic effect of and in this tropical dry deciduous forest.
